Has anyone mounted their holley dominator and distribution blocks somewhere in the back seat? I was thinking about making a rear seat delete that has a hidden enclosure that can be accessed/uncovered and then mounting the holley stuff under it. I want to be able to access everything easily without pulling the dash apart to get to it. I'm assuming wires on the harness would have to be elongated as most of the mounting locations I've seen have been on the firewall or on a metal sheet fastened to the passenger side cage door bar/floor bar.
That would probably be long enough. If you go this route please post pics of how you fabricated it. I was thinking light mdf board and some gray speaker box carpet.
I was thinking aluminum to be lighter.. but was also considering fabricating a panel with hinges that drops down in place of the passenger kick panel.. probably be a winter project.
In my '81 Camaro I mounted the Dominator under the carpeting of the passenger footwell. It is invisible there and still easily reachable.
The first picture shows it sitting on the floor during the initial testing . The second picture shows it mounted to the footwell with the excess harness draped around it and clamped into position. The silver is Dynamat heat protection. The carpet is folded up and ready to cover it all. My battery is in the trunk and the supplied power harness reached it fine; it runs under the rocker covers, under the rear seat and into the trunk. The big red cable is my main battery cable going to engine compartment.
I thought of that, but I didn't want to procure all the different connectors and pins, and then have to crimp everything to assemble.
Out of sight out of mind now.
the 15' harness I was looking at has the ECU connectors and I thought to keep my injector and coil harnesses intact, so just the main connector for those. and my Trans harness i was going to run under the console and through the floor for a cleaner look.
I don't think it would be too bad... What else you got to do all winter
How many wires need re-pinned? Cant be much more than doing a fuse/relay box relocation and repining all those wires.
The 558-126 unterminated harness doesn't have any connectors for any of the engine side wires. So all of the sensor connectors need to be added and properly terminated. You also need to be aware whether your engine is gen 3 or gen 4, because there are voltage differences for numerous sensors.

The Dominator trans harness is a separate harness and is not part of the main unterminated harness.
I was planning on getting all this but it looks like I'll have to verify part numbers to ensure certain harnesses are not terminated. Did you guys buy all these harnesses or did you make your own on some of them?
The top list looks about right, except I don't think you need the 558-200 when you have the 558-201.
Obviously you don't need the VK080022 if you buy the items separately. That kit did not work for me because it included parts I wouldn't use and the discount was minimal or perhaps none at all.
I think you will want (need?) two of the Wideband O2 sensors.
I also bought the dual-throttle-body harness.
Shop around, IIRC I bought most everything including the main Dominator from a high-reputation ebay seller for 10% below Summit's pricing
Ya there are vendors on facebook with deals for sure. I thought you couldn’t do dual wideband on the holley? Maybe it was the terminator X and not the Dominator that could only do single band? Too bad the common Bosh wideband sensors won’t work with the holley.

The Bosch is an option or the NTK with the dominator the way I read.. but I think for Dominator the Bosch is Holley specific whereas for Terminator it is the universal 4.9.. maybe that is what you meant.

I believe that is correct. I was told I couldn’t use my Bosch 4.9 with the dominator.

You definitely can and probably should run two widebands with the Holley even though the main LS harnesses only have connection for one. For the 2nd wideband Holley has a special I/O harness #558-401 with a wideband connector and many unterminated I/O lines. This might be an alternative to the 558-400 you listed. The Holley display systems show the AF ratio of both widebands.

Price isnt everything when purchasing an EFI system. Support after the sale is huge if you have any issues or need tech support. I may not be the cheapest but can 99% of the time price match any legit dealer but instead of tying to sell it the cheapest I just offer more with the product like a free base tune with dominator systems for example. Since I sell, install and tune these systems daily I can provide first hand tech support vs someone just reading some notes on a screen. Also if someone isnt an authorized dealer you wont have proof of purchase for warranty. If there is an issue with a product we handle it vs you sitting on hold trying to handle it yourself. Just some things to think about before spending thousands of dollars on an efi system.

Correct. I had listed both wideband harnesses because I wasn't sure which one I was going to go with. Which items from the VK080022 did you identify that you would wind up not using?
